These are very easy to drive in using a hammer drill. No rawlplugs needed. The drill attachment fits loosely over the fitting so the rotation of the drill does not actually turn the fitting. It is the hammer action that causes to self-tap its way into the block. As a result, it does not remove any material from the block nor does it create any dust. The resulting fix feels very secure. The fitting doesn't have a head like a screw but easily buries itself into the wood. Not sure how you would remove it though if you put it in the wrong place. Presumably, you would just knock it clean through the wood into the block and leave it.
